A Groups.io group can be synchronized (synced) with an external service, which means that members of the external service automatically can be made members of the group. Automatic syncing occurs hourly. 

Currently, the only service that a Groups.io group can sync with is Slack. Once you set up the connection between your group and your Slack team, you can view which members are a part of one and not the other and synchronize them.

To synchronize your group members with a Slack team:

  1. Go to the group’s website and display the Sync Settings page:
    Desktop browser: In the left menu, select Admin > Membership > Service Sync.
    Mobile device: At the bottom of a page, tap More, then select Admin > Membership > Service Sync on the More menu.
  2. On the Sync Settings page, from the Service list, select Synced with a Slack Team. The Authenticate with Slack button appears.
  3. Click or tap Authenticate with Slack and then sign in to your Slack workspace. Ensure that you give Groups.io permission to access the workspace. After you are signed in, you are returned to the Sync Settings page in your group.
  4. Under Auto Sync Type, select the type of synchronization you want to use. Under Join Channels, select the applicable channels.
  5. Click or tap the Update Sync button at the bottom of the page. The result depends on the Auto Sync Type option you selected. If it was:
    • One of the Pull or Push options: The members in Groups.io and Slack are synchronized according to your selection.
    • No Automatic Sync: Groups.io displays the Sync Dashboard page, which contains two tabs. Each tab lists the people who are not members of the other. You can use those tabs to manually select the members of each team that you want to sync with the other team:
      • On the Groups.io Members tab, which lists the group members who are not members of the Slack team, select the group members you want to add to the Slack team and click or tap the Add to Slack button.
      • On the Slack Members tab, which lists the Slack team members who are not members of the Groups.io group, select the members you want to add to the group and click or tap the Add to Groups.io button. 

Note: When you select No Automatic Sync, you can click or tap the Sync Dashboard button (next to the Update Sync button) at any time to view the Groups.io Members tab and Slack Members tab. The Sync Dashboard button is disabled when you select a Pull or Push sync option.
